Hi,
I have the below data for example

{ "a": { "b": "", "c": {}, "d": [ { "e": "", "f": "s", "g": { "h": "", "i": "", "j": "" } } ], "k": {} }, "l": { "m": { "t": "u" }, "n": "v", "o": { "p": "̊w", "q": { "x": 1, "y": 1, "z": 1, "a1": 0 }, "e": a2 } } } 

Now, I aim to modify the e field within this structure. While I lack the Protobuf definition and message name, I possess the field number path to access e. I plan to generate a temporary message using the provided field numbers, decode the binary, modify the value, and then encode it again.

However, I've encountered an issue: when I decode the modified message alongside the actual message and its definition, I experience data loss and the disappearance of other fields.

Please guide on performing this task without experiencing data loss or losing other fields in the process.
